A theoretical study of the steady-state model for measuring regional cerebral blood flow and oxygen utilisation using oxygen-15.
There is a growing interest in the tomographic measurement of regional cerebral blood flow and oxygen utilisation using continuous inhalation of C15O2 and 15O2. This paper examines the influence of certain assumptions in the underlying steady-state model. Estimations are made for possible errors in the actual measurement of these quantities in grey and white matter.
